Research on the effects of Direct Instruction (DI) among students with Autism Spectrum Disorder (ASD) has only recently emerged. A benefit of DI is that it can be implemented with groups of students, which makes it potentially a cost effective method of instruction for some skills. In this study, we examined the effects of DI on teaching secondary students with ASD to answer three "wh-" questions. Using a multiple probe design across behaviors, results indicated the participants mastered two of the three "wh-" question types and made progress with the remaining question type. These results are discussed along with implications for educators instructing students with ASD.
